 * @ingroup GetPowerTmpBufferFactorSize for V220
 * @brief The calculation of the Round interface requires the developer to reserve or apply for temporary space. The
 *  relationship between the maximum temporary space (maxTmpBuffer) and the space occupied by the input (inputSize x
 *  typeSize) is as follows: maxTmpBuffer = maxLiveNodeCnt * inputSize * typeSize + extraBuf
 *  This interface is used to obtain maxLiveNodeCnt and extraBuf.
 * @param [in] baseIsTensor : whether base input is a Tensor
 * @param [in] expIsTensor : whether exponent input is a Tensor
 * @param [in] typeIsInt : whether the src type is int
 * @param [in] typeSize : src tensor dtype size
 * @param [out] maxLiveNodeCount: the multiple of the maximum temporary space to the input occupied space
 * @param [out] extraBuffer: the size of the extra temporary space
